BICYCLE-ALARM.

SPECIFICATION forming part of Letters Patent No. 561,667, dated June 9, 1896, Application filed February 24, 1396. Serial No. 580,543. (No model.)

such as will enable others skilled in the artto which it most nearly appertains to make, use, and practice the same.

This invention relates to improvements in bicycle-alarms; and it consists in the arrangement and construction of the parts, as hereinafter set forth.

The objectwhich this invention has in view is the production of a loud and continuous alarm to warn pedestrians of the approach of the bicycle.

In the drawings, Figure 1 is a side elevation of the invention as applied to a bicycle. Fig. is a detail view of the hand-lever.

For the purposes of description with reference to the drawings we will let the letter A designate the pivoted rod upon which the vibrator B is mounted. The red A is mounted in suitable clips A A-, which secure it to the head and forks of the machine. These clips are clamped rigidly in position by suitable screws to pull the ends of the clips together. The clip A is slotted to receive the set-screw A which enters the rod A and supports it in position, and serves as a stop to limit the throw of the rod and vibrator.

The vibrator B consists of a thin flat piece which is extended in front so that its outer end will be thrown against the spokes of the wheel when the rod is rotated. This vibrator may be constructed of metal, wood, or other suitable material; but that most preferred by me is wood of a springy nature. It is rigidly secured to the rod A by thumb or set screw, and may be set on the side of the rod, as shown, or inserted in slots provided for it in the rod. This vibrator is usually provided with a small bell B in the nature of a sleighbell, which is rung by the movement of the vibrator. These bells are suspended on the vibrator in any suitable manner and are preferably detachable therefrom. I

In its normal position the rod A holds the vibrator B away from the spokes of the wheel.

In this position it is maintained by the spring 0, which is coiled about the rod and secured to it and the clip A in such manner as to keep the set-screw A against the end of the slot in the clip A as shown. Vihenever the rod A is rotated, so as to throw the end of the vibrator against the spokes, it is done so against the strain of the spring 0, which will return the rod to its normal position when the rotating strain is removed.

To rotate the rodA to throw the end of the vibrator against the spokes of the wheel, I have provided the hand-lever D and its connections, as shown in Fig. 2 of drawings. From the side of the rod A is extended the pin D, to which is pivotally connected the connecting-link D The link I) is likewise connected to the end of the hand-lever D. The hand-lever is pivotally mounted on the handle-bar of the bicycle, as shown. When now the hand-lever is raised at its free end, the other end is depressed, carrying the end of the link D downward and to a level with the pin D. The effect of this is to push the pin D away from the leverD by rotating the rod A. This rotation of the rod throws the end of the vibrator against the spokes of the wheel, which, in a rapidly-revolving wheel, strike the end of the vibrator in rapid succession so long as the hand-lever is thus raised. This causes a rapid and violent agitation of the vibrator and the bell or other sounding device which is mounted thereon.

The sound produced by this alarm is sudden, penetrating, and continuous for as long as the hand-lever is operated.

Having thus described this invention, what I claim is- In a bicycle-alarm, the combination of a vibrator pivotally mounted on a revoluble rod supported on the frame of a bicycle, said vibrator being adapted to be turned to impinge upon the spokes of a wheel, and suitable devices for so turning the revoluble rod, substantially as described.

In testimony whereof I have hereunto set my hand this 8th day of February, 1898.
